Mobifreeze

Mobile ultra low temperature freezer

Mobile ultra low temperature storage for controlled cold chain transport

The LAUDA Mobifreeze is a battery-powered ultra low temperature chest freezer ideal for the transport of temperature-sensitive materials under controlled conditions. With active temperature control, the system supports reliable cold chain maintenance during intralogistics and inter-factory transport in road logistics.

The freezer provides adjustable temperatures from -86 to -50 °C and is suitable for transporting sensitive materials that require the same validated storage conditions during transport. An alternative temperature range of -40 to 0 °C is also available to meet pharmaceutical GDP logistics requirements.

Unlike conventional transport methods using dry ice, the Mobifreeze provides active cooling throughout transport without the need for consumables.

Controlled transport without dry ice

The Mobifreeze offers an alternative to dry ice for the transport of temperature-sensitive samples. Eliminating dry ice removes the associated requirements for ventilation and personnel protection while reducing the costs associated with its use.

The refrigeration system uses natural refrigerants and does not rely on dry ice or phase-change materials (PCM/PWM), providing an environmentally friendly operating principle while reducing dependence on consumables.

Battery-powered operation

A high-performance lithium iron phosphate battery enables flexible switching between mains and battery operation. When mains power is available, the system automatically switches to mains operation while recharging the battery.

At a storage temperature of -80 °C, the battery can bridge transport phases of up to four hours without an external power supply. The battery backup also maintains the display and alarm functions during a power failure.

Reliable cold chain monitoring

The Mobifreeze supports pharmaceutical GDP logistics by maintaining controlled transport conditions throughout the cold chain.

If preset temperature limits are exceeded, the freezer generates both acoustic and visual alarms. An integrated data logger records temperature and alarm data, allowing transport conditions to be documented.

The possibility of stationary and mobile hybrid use reduces the need to transfer samples between storage and transport equipment, helping to minimize the risks of damage, mix-ups and contamination.

Construction and operating features

The interior of the Mobifreeze is manufactured entirely from stainless steel. Stainless steel floor assemblies and forklift skids (material 1.4404) facilitate safe transport and handling.

The freezer includes a standard feed-through with an internal diameter of 13 mm for external control sensors.

Operation is managed through a touchscreen control unit with a digital display for entering and viewing safety-related settings. A transparent, lockable cover protects the battery monitor together with the battery and power switches.

The refrigeration system uses fully hermetic high-performance compressors and is designed for energy-efficient, maintenance-free operation. Vacuum insulation panels combined with impermeable foamed polyurethane insulation provide high temperature stability while reducing energy consumption.

Additional one-piece insulating cover plates are positioned above the usable storage space to further improve insulation.

Fields of application

Intralogistics

The Mobifreeze supports cold chain maintenance throughout internal logistics processes, including incoming goods, storage, internal transport and outgoing goods.

Typical applications include:

• Short-distance transport of sensitive and valuable materials
• Controlled transport under the same conditions as storage

Cold chain logistics

The Mobifreeze is designed for the transport of temperature-sensitive products requiring active cooling and controlled low-temperature conditions.

Typical applications include:

• Transport without dry ice
• Maintaining the required product temperature
• Active cooling during transport

Hybrid use

The combination of stationary storage and mobile transport allows products to remain in the same freezer throughout the logistics process. This reduces transfer steps while minimizing the risk of damage or contamination.

Typical applications include:

• Pharmaceutical research and production
• Long-term pharmaceutical storage and transport
• Sample storage and transport in research and development laboratories
